This stainless steel constructed dissolved oxygen sensor is designed for maximum accuracy and reliability. Modular and robust design along with state-of-the-art interior sensor design allows for easy disassembly for maintenance. PTFE/silicone membrane designed with an internal steel mesh makes the membrane more rugged, drastically improving repeatability of these senors in bioprocess applications.
